Title: Production of polyethylene terephthalate
Inventor: AKAHA YOSHIO
IPC: C08G63/183
Filed: 1994-01-20
Abstract: PURPOSE:To produce polyethylene terephthalate with stable qualities by controlling the degree of vacuum in the final reactor using an estimation of the melt viscosity of the polymer taken out of the final reactor in the continuous polycondensation process for producing the polymer. CONSTITUTION:Polyethylene terephthalate (PET) is continuously produced by the polycondensation of bis(beta-hydroxyethyl) terephthalate (BHET) melt in the presence of a catalyst using reactors arranged in series while removing ethylene glycol under a reduced pressure. The polycondensation is conducted while controlling the degree of vacuum of the final reactor by estimating the viscosity of the polymer taken out of the final reactor using an estimation model prepd. in advance. The model expresses the change in the degree of vacuum and the change with time in the melt viscosity of PET at constant vigorousness and temp. of agitation in the final reactor by using the equation (wherein the left side is the viscosity at the time k+1; aj is a coefficient; and DELTAu is the amt. of operation of the degree of vacuum) obtd. from actual production data, inputs those changes into a computer, and estimates and controls the degree of vacuum.

Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce the load of a motion controller by producing the movement data per unit time based on the moving direction information and the moving speed information and then sending the movement data to the controller as a movement command. SOLUTION: A high speed H, a medium speed M or a low speed L is designated. If the moving speed is previously set at 10mm/see together with the transmission cycle set at 20ms respectively at the speed L, a CPU 3 receives the velocity information on the speed L with the movement unit set at 1μ and the designated speed L. Then the CPU 3 sends the movement data of the +x direction where the data are added by 200μ every 20ms of unit time X200, X400, X600 and X800 to a controller every time a key +x is pushed. The data are reduced with push of a-x key, and the moved variable has no change as long as + or - key is not pushed. When the speeds M and H are selected, the movement change value differs according to the moving speeds set previously at the speeds M and H respectively.

Abstract: PURPOSE: To improve gate electrodes in inter-electrode insulation peoperties and to enhance a semiconductor substrate and the gate electrodes in dielectric properties between them by a method wherein an insulating film which isolates the gate electrodes from each other is composed of a second oxide film and a second nitride film. CONSTITUTION: A first oxide film 22 and a first nitride film 23 are successively formed on a semiconductor 21.

Title: Semiconductor integrated circuit
Inventor: YANAGISAWA MAKOTO
IPC: H01L21/82
Filed: 1994-01-21
Abstract: PURPOSE:To reduce the pitch of fuse arrangement by forming a second well under the cutting target portion of each of a plurality of fuses placed on one line of first wells on the front side. CONSTITUTION:Fuses 4/1-4/14 are arranged at an equal interval, and P wells 521-5214 are formed below them, respectively. Overpower of a laser beam may bring some or all of fuses cut off into contact with a p-type silicon substrate 42 through their residues. Since the potential of the individual fuses is at a supply voltage VCC or 0V at the time of operation, leakage current is prevented from being generated from fuses in contact with the p-type silicon substrate 42 as long as the contact is limited within the corresponding ones of the P wells 521-5214. This makes it possible to increase the number of fuses without increase in chip area.

IPC: B65H13/00
Filed: 1989-01-12
Abstract: PURPOSE:To reduce the loss by allowing a pressing roller to press the outer periphery of a new web when a detection sensor detects the edge of an old web and by setting the length from the edge to a pressing position through a dancer roll, longer than the sum of the outer peripheral length of the new web roll and the traveling length for the time for pressing by the pressing roller. CONSTITUTION:When the edge We of an old web is detected by a sensor 14, the old web W1 is pressed onto the outer periphery of a new web roll R2 by a pressing roller 8. At the time point when the pressing roller 8 reaches a pressing position P, the length between the position P to the web edge We through a dancer roll 11 is set longer than the sum of the outer peripheral length of the new roll R2 and the traveling length for the time up to the lowering of the pressing roller 8. Therefore, the length from the superposed relaying part at the P point to the web edge We of the old web W1 is at most nearly equal to the outer peripheral length of the new roll R2, and the loss of the old web W1 can be reduced.

Filed: 1985-01-18
Abstract: PURPOSE:To input stably a moving image by inputting a certain quantity of light to a camera independently of the speed of a moving object. CONSTITUTION:A photodetector 5 generates the next pulse when receiving the light from a light projector 4b, and the time measurement is terminated when this pulse is detected by a microprocessor 13. Since the distance between an ITV camera 6 and the photodetector 5 is known, a shutter 7 is opened through a shutter controller 10 with a delay time (TIMER) characteristic, and simultaneously, a gate 17 is opened to send vertical and horizontal synchronizing signals from an oscillator 18 to each device.
